Abstract

A double-radiant-source framework used for a container detecting system, which belongs to the technical field of radiation detection, having a horizontal accelerator, a vertical accelerator and a gantry tower composed of a left vertical girder, a right vertical girder, an upper cross girder, and a lower cross girder. A horizontal collimator and a vertical collimator are disposed in front of the frontal face each of the horizontal accelerator and the vertical accelerator. The horizontal collimator and the vertical collimator are fixed on the left vertical girder and the upper cross girder of the gantry tower, respectively. The radiation beams defined by the horizontal collimator and the vertical collimator are two planes oriented parallel to each other. A double-detector arm is disposed inside the right vertical girder of the gantry tower, and detector modules are disposed inside the double-detector arm for receiving the two different planes of radiation beams defined by and emitted from the horizontal collimator and the vertical collimator. Detector modules are disposed inside the upper cross girder and the lower cross girder respectively for receiving separately radiation beams defined by and emitted from the horizontal collimator and the vertical collimator. The container detecting system can reduce the area covered by the scanning channel of the system, and make the transportation, installation and use convenient, and improve the quality of the detected images.

Description

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a radiant source scan channel of an automatic scan type radiation detecting system for detecting large objects, and more particularly, to a double-radiant-source scan channel structure, which belongs to the technical field of radiation detection.

[0002] Container freight / vehicle detecting system is the major detecting device that the customs needs. So far, customs in most of the countries mainly adopts a method of opening the container or a method of single-radiant-source radiation imaging in the detection of the container trucks passing through the customs. The detection method of opening the container and tearing open the freight needs a long time, with a low detection amount per day, and has a high detection cost, which seriously affects the speed of the container trucks passing through the customs. In order to solve this problem, a detecting system using single-radiant-source radiation imaging was developed. The...
